WalkthroughComp was done by Emily Short, where she wrote out a telegram of a bizarre walkthrough for a nonexistent game, and then you were to write that game.
This game is one of the biggest responses to that; however, it's too big. The game is full of text dumps, and the environment (inside a VR machine) just veers wildly from genre to genre and location to location.
It must have taken a lot of effort, but it needed more coherence, I think.
